Answer:
A, The water moving away
Explanation:
When the pebble hits the water the surface tension breaks causing the water to separate away and make a ripple in the water.
Answer:
Weight is just how heavy something is. Mass is the quantity of inertia possessed by an object. Another way of explaining mass is how much matter is in an object or how much "stuff" is in an object. Another important difference is that weight is a force and mass is not.
Explanation:
Answer:
<em> The heat diffusion equation for a 1-D cylindrical, radial coordinate system with internal heat generation is given as</em>
<em> </em><em></em>
<em>This equation is comparable to equation 2.26 when φ and z terms are considered 0.</em>
Explanation:
As per the given statement, <em>heat diffusion equation for a one-dimensional, cylindrical, radial coordinate system with internal heat generation </em>is given as the condition.
Let us consider a control volume of unit thickness with volume as given below perpendicular to the paper.
As per the conservation of energy
Now using the Fourier's law in 1-D coordinate system
Similarly
Substituting these values in the energy balance equation gives
Dividing both sides with 2πr dr
The heat diffusion equation for a 1-D cylindrical, radial coordinate system with internal heat generation is given as
This equation is comparable to equation 2.26 when φ and z terms are considered 0.
The microscope slide needs to be transparent so it allows the light to pass through it, which causes the microscope to magnify the slide and the object on the slide. The light must come from beneath it in order for you to the object clearly.
Answer:
230 ohm
Explanation:
V = 12 V
R1 = 50 ohm
R2 = 80 ohm
R3 = 100 ohm
This is the circuit containing three resistors which are connected in series and a battery is also connected in the circuit.
The formula for the equivalent resistance when the resistances are connected in series is given by
Where, Rs be the equivalent resistance of the three resistances which are connected in series.
Rs = 50 + 80 + 100
Rs = 230 ohm
Thus, the total amount of the resistance in the circuit is the equivalent resistance which is equal to 230 ohm.
